There are six major kingdoms that fall under the three domains that organisms can be grouped into. Each of these kingdoms has distinct characteristics. Classification starts with these criteria:
Number of Cells (Unicellular or Multicellular).
Type of Cells (Prokaryote or Eukaryote).
Method of Nutrition (Autotroph or Heterotroph).

Where do we find Archaebacteria? Are these creatures made of 1 cell or many cells?
Where do we find Eubacteria? Are these creatures made of 1 cell or many cells?

How is Protista classified? Are these creatures made of 1 cell or many cells?

Are Fungi made of 1 cell or many cells?

Are Plants made of 1 cell or many cells? Define Autotrophic

Are Animals made of 1 cell or many cells? Define Hetrotrphic
